Converting Feet and Inches to Centimeters:

To convert feet and inches to centimeters, use the following formulas:

1. Convert feet to centimeters: 1 foot=30.48 cm1 \text{ foot} = 30.48 \text{ cm} Feet×30.48=cm\text{Feet} \times 30.48 = \text{cm}
2. Convert inches to centimeters: 1 inch=2.54 cm1 \text{ inch} = 2.54 \text{ cm} Inches×2.54=cm\text{Inches} \times 2.54 = \text{cm}
3. Total centimeters: (Feet×30.48)+(Inches×2.54)(\text{Feet} \times 30.48) + (\text{Inches} \times 2.54)

Example Conversion: For 5 feet 7 inches: (5×30.48)+(7×2.54)=152.4+17.78=170.18 cm(5 \times 30.48) + (7 \times 2.54) = 152.4 + 17.78 = 170.18 \text{ cm}

Explanation: Feet and inches are commonly used in the imperial system, while centimeters belong to the metric system. Converting between these two units is useful for scientific calculations, international travel, and understanding height in countries using the metric system.

The conversion factor for feet to centimeters is 30.48, meaning each foot adds that much height. Similarly, 2.54 cm per inch means every additional inch increases the total length accordingly.

For instance, someone who is 5 feet 10 inches tall can be converted as follows: (5×30.48)+(10×2.54)=152.4+25.4=177.8 cm(5 \times 30.48) + (10 \times 2.54) = 152.4 + 25.4 = 177.8 \text{ cm}

This calculation is useful in medicine, sports, and engineering. Many countries like the USA use feet and inches, while most others, including Europe and Asia, use centimeters.

Thus, understanding this conversion allows for better communication in height measurements, tailoring clothes, and architectural designs.
